Note: The cross bearing retaining ring may be steel (conventional design) and plastic (disposable ring that is cut off during disassembly). The disassembly/assembly process is the same in both cases.
Disassembly
Warning: Never clamp the driveshaft in a vice by the shaft tube. Distortion of the tube may cause the shaft to be out of balance. Clamp the shaft only by the flange of the joint fork. Do not scratch or burr the seal working surface.
1. Install the cardan shaft parallel to the press table.
2. Mark the front and rear ends of the drive shaft pipe.
3. Remove the retaining rings from the crosspiece bearing caps.
4. If the ends of the steel retaining ring cannot be brought together, tap the bearing cap lightly to loosen it.
5. Position the universal joint so that the bottom of the fork rests on the socket wrench (tool head) size 30 mm.
6. Install a special fork on the open diameters of the crosspiece bearings and push out the lower crosspiece bearing.
7. If the bearing is not completely removed, place a spacer between the bearing seal and the bearing ring and press out the bearing in the manner described above.
8. Turn the cardan shaft over. Press out the opposite crosspiece bearing.
9. Mark the relative positions of the sliding fork and the propeller shaft tube.
10. Remove the crosspiece of the joint.
11. Remove the remaining parts from the hinge fork.
12. Disassembly of the front hinge is carried out in the manner described above.
13. Clean the grooves for the retaining rings and assess their condition. Replace the hinge fork if necessary.
14. Clean the bearing seats of the crosspiece in the fork, assess the condition of the seat, replace the fork if necessary.
Assembly
1. Remove the remaining bearings from the crosspiece.
2. Install the bearing into the side seat of the fork. Turn the fork over.
3. Insert the crosspiece of the joint into the fork.
4. Press the bearing in until its end cap is flush with the fork.
5. Install the bearing on the opposite side of the fork.
6. Make sure that the crosspiece journals are correctly oriented in the bearings.
7. Press in the second bearing, if there is any distortion, stop the assembly operation and start all over again.
8. Press the bearings until the grooves for installing the retaining rings are open.
9. Install the retaining rings.
10. Check the reliability of the ring snap. The bearing may "spring" on the grease and prevent the ring from fitting, seat the bearing with a sharp blow of a hammer.
